# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

@mafintosh said most of this, I just wrote it down

how to destroy/end streams in node >= 0.10

• usually you call .destroy() if it has .destroy
• if it doesnt have .destroy you are out of luck and the stream should upgrade to use e.g. newer through2
• in request you call .abort() (this should get fixed to use .destroy())
• .end() tries to end the stream gracefully

what about close

Simply register the two helpers "section" and "yield-section", and start right away!

See example below, using ember-cli:
